Active Deformation Across the Western Anatolian Extensional Province (Turkiye) From Sentinel-1 InSAR.

ABSTRACT: Quantifying interseismic deformation of fault networks which are predominantly deforming in a north-south direction is challenging, because GNSS networks are usually not dense enough to resolve deformation at the level of individual faults. The alternative, interferometric synthetic aperture radar (InSAR), provides high spatial resolution but is limited by a low sensitivity to N-S motion. We study the active normal fault network of Western Türkiye, which is undergoing rapid N-S extension, using InSAR. Since most faults in the study region are normal faults, we overcome the low N-S sensitivity by focusing on the vertical deformation component, which presents its own challenges. Sediment-filled grabens show rapid anthropogenically induced subsidence, whereas urban areas tend toward erroneous
